You could do it with WDDX -- CF has a tag, cfwddx, that
converts/transmits CF arrays on the server to _javascript_ arrays on the
client.
CFWDDX is the easiest way to go if you have a small number of users and
a small amount of data.
CFWDDX sends/receives the data and the _javascript_ code (about 22K) to
manipulate the data on the client.
Your data would be about 100 characters for each customer, so:
100 x 50 customers = 5,000 characters of raw data for 50 customers
5,000 x 256% wddx packet (XML) overhead * = 12,800 of data and XML
12,800 data & XML + 12k wddx js code = approximately 25K of data being
sent, over and above the html in the page.
So, how many of these 25K hits do you expect concurrently.
If just a few, WDDX is prolly OK.
But if the number of customers or number of concurrent users grows
significantly, you will have a bandwidth problem.
There are other ways to accomplish this at much less overhead -- one is
the concept of thinArrays,
This is an open-source solution that requires a little (not much) more
work on your part than the wddx tag
I will send you a write off list because it is too big to post.
Then look at cfwddx vs thinArrays & decide what's best for you.
* the 256% wddx overhead is approximate, but was observed in several
typical applications
By contrast, thinArrays add approcimately 13% Overhead
